This is why I recommend posting an actual image of your character. Your appearance isn't clear enough. If you're gonna put a description of your character rather than give us an image, you need to be much more descriptive. Also, your "Back story" isn't actually a Back story. A Back story explains step-by-step how your character managed to get into this academy. All I see is that your character enjoys playing basketball. Not to be rude or anything, but this definitely needs improvement.

Your history needs the most improvement. Your history is the story of your character's life; a biography, if you will. Please start your history over and do what is asked. I'd highly recommend being more descriptive with everything at this time to make a better impression.
